Solid textile detergent formulation based on glycin-N, N- diacetic acid derivatives with a highly reduced proportion of other anionic surfactants

ABSTRACT

The invention relates to a solid textile detergent formulation containing (A) 1-60 wt. % inorganic builders based on crystalline or amorphous aluminosilicates, crystalline or amorphous silicates, carbonates and/or phosphates, (B) 1-40 wt. % of one or several glycin-N, N-diacetic acid derivatives of formula (I), wherein R stands for an organic radical and M means hydrogen or a cation, (C) 0-6 wt. % anionic surfactants with one or several sulphate groups, one or several sulphate groups or one or two carboxylate groups and (D) 0.5-50 wt. % non ionic surfactants.

The present invention relates to a solid textile detergent formulation comprising inorganic builders, glycine-N,N-diacetic acid derivatives, with or without small amounts of other anionic surfactants, nonionic surfactants and, if desired, further customary constituents.

Surfactants are the most important group of detergent ingredients. Their content in conventional reduced-phosphate or phosphate-free powder detergents is usually from 10 to 25% by weight. Surfactants detach liquid (oily) and solid fiber soiling during the washing process. However, the detergency of anionic surfactants, in particular, decreases with increasing water hardness. Builders, such as zeolites, are therefore used, their primary purpose being to increase the washing performance of the anionic surfactants by binding the calcium and magnesium ions that are responsible for water hardness.

Some solid soiling contains alkaline earth metal ions, in particular calcium ions. Removal of the calcium ions leads to a loosening of the soil structure and thus facilitates soil detachment from the fiber. In this connection, surfactants require the assistance of water-soluble complexing agents for calcium.

Glycine-N,N-diacetic acid derivatives are surface-active substances of this type. They reduce the surface tension of the washing water and effect soil detachment. They form complexes with Ca and Mg ions, remove particularly effectively calcium-containing soiling and, additionally, support the inorganic builders in their role of softening the washing water and preventing the build-up of fabric incrustations.

The use of said glycine-N,N-diacetic acid derivatives in solid textile detergent formulations is already known from WO-A-97/19159. This patent describes solid textile detergent formulations which comprise, as organic cobuilders, up to 40% by weight of such glycine-N,N-diacetic acid derivatives; these textile detergent formulations further comprise usual amounts of customary anionic surfactants, ie. about 10% by weight or more.

It is an object of the present invention to provide a solid textile detergent formulation in which the content of traditional anionic surfactants is drastically reduced and which comprises a detersive (surface-active) substance which is able to bind calcium and magnesium ions.

We have found that this object is achieved by a solid textile detergent formulation which comprises

(A) from 1 to 60% by weight of inorganic builders based on crystalline or amorphous alumosilicates, crystalline or amorphous silicates, carbonates and/or phosphates,

(B) from 1 to 40% by weight of one or more glycine-N,N-diacetic acid derivatives of the formula I

(D) from 0.5 to 50% by weight of nonionic surfactants.

The sum of all the detergent components given above and below is at most 100% by weight, including residual quantities of water.

Suitable inorganic builders (A) are in particular crystalline or amorphous alumosilicates having ion exchange properties, such as, in particular, zeolites. A variety of zeolite types are suitable, in particular zeolites A, X, B, P, MAP and HS in their Na form or in forms in which Na has partially been replaced by other cations, such as Li, K, Ca, Mg or ammonium. Suitable zeolites are described in EP-A 038 591, EP-A 021 491, EP-A 087 035, U.S. Pat. No. 4,604,224, GB-A 20 13 259, EP-A 522 726, EP-A 384 070 and WO-A 94/24251, for example.

Examples of suitable crystalline silicates (A) are disilicates or sheet silicates, eg. δ-Na₂Si₂O₅ or β-Na₂Si₂O₅ (SKS 6 and SKS 7, Hoechst). The silicates can be used in the form of their alkali metal, alkaline earth metal or ammonium salts, preferably as Na, Li and Mg silicates. Amorphous silicates, for example sodium metasilicate, which has a polymeric structure, or amorphous disilicate (Britesil® H 20, Akzo) can also be used.

Suitable inorganic carbonate-based builder substances (A) are carbonates and hydrogencarbonates. These can be employed in the form of their alkali metal, alkaline earth metal or ammonium salts. Preference is given to carbonates and hydrogencarbonates of Na, Li and Mg, in particular sodium carbonate and/or sodium hydrogencarbonate.

Phosphates which are customarily used as inorganic builders (A) are polyphosphates, for example pentasodium triphosphate.

Said components (A) can be used individually or in mixtures with one another.

Component (A) is preferably present in the textile detergent formulation according to the invention in an amount of from 5 to 50% by weight, in particular from 10 to 45% by weight.

In a preferred embodiment, component (B) comprises compounds I in which R is a radical having at least 7 carbon atoms.

In a particularly preferred embodiment, component (B) comprises glycine-N,N-diacetic acid derivatives I in which R is a linear or branched unsubstituted C₇- to C₃₀-alkyl or C₇- to C₃₀-alkenyl radical, which may be interrupted by up to 5 nonadjacent oxygen and/or nitrogen atoms; said nitrogen atoms may carry hydrogen or C₁- to C₈-alkyl groups.

Compounds I are used in the form of the free acids or their alkali metal, alkaline earth metal, ammonium and substituted ammonium salts. Salts of this type which are especially suitable are the sodium, potassium and ammonium salts, in particular the trisodium, tripotassium and triammonium salts, and also organic triamine salts having a tertiary nitrogen atom.

Particularly suitable parent bases for the organic amine salts are tertiary amines, such as trialkylamines having from 1 to 6 carbon atoms in the alkyl moiety, eg. trimethyl- and triethylamine, methyldiethylamine or tricyclohexylamine, and trialkanolamines having 2 or 3 carbon atoms in the alkanol radical, preferably triethanolamine, tri-n-propanolamine or triisopropanolamine.

Alkaline earth metal salts which may be used are, in particular, the calcium and magnesium salts.

It is possible to employ the racemates of compounds I or the two enantiomers with respect to the a-carbon atom in the glycine backbone.

Suitable linear or branched alk(en)yl radicals as R are C₅- to C₃₀-alkyl and -alkenyl, particularly linear radicals derived from saturated or unsaturated fatty acids. Examples of individual R radicals are: n-pentyl, isopentyl, tert-pentyl, neopentyl, n-hexyl, n-heptyl, 3-heptyl (derived from 2-ethylhexanoic acid), n-octyl, isooctyl (derived from isononanoic acid), n-nonyl, n-decyl, n-undecyl, n-dodecyl, isododecyl (derived from isotridecanoic acid), n-tridecyl, n-tetradecyl, n-pentadecyl, n-hexadecyl, n-heptadecyl, n-octadecyl, n-nonadecyl, n-eicosyl and n-heptadecenyl (derived from oleic acid). R can also be a mixture, in particular one derived from naturally occurring fatty acids and from technical-grade acids produced synthetically, for example by oxo synthesis.

The C₅- to C₁₂-alkylene bridges A are especially polymethylene groups of the formula —(CH₂)_(t)—, where t is a number from 5 to 12, in particular from 5 to 8, ie. pentamethylene, hexamethylene, heptamethylene, octamethylene, nonamethylene, decamethylene, undecamethylene and dodecamethylene. Hexamethylene and octamethylene are particularly preferred. However, branched C₅- to C₁₂-alkylene groups can also occur, eg. —CH₂CH(CH₃)CH₂CH₂—, —CH₂C(CH₃)₂CH₂—, —CH₂CH(C₂H₅)CH₂— or —CH₂CH₂CH(CH₃)CH₂CH₂—.

The C₅- to C₃₀-alkyl and alkenyl groups can carry up to 5, in particular up to 3, additional substituents of said type and be interrupted by up to 5, in particular up to 3, nonadjacent oxygen atoms and/or nitrogen atoms. Examples of such substituted alk(en)yl groups are —CH₂CH₂—O—CH₂CH₂—O—CH₃, —CH₂—O—(CH₂)₄—OH, —CH₂CH₂—N(CH₃)CH₂CH₂CH₃—, —(CH₂)₅—N(CH₃)₂ or —(CH₂—O—CH₂)₅—COOCH₃. Also of interest are substituted alk(en)yl groups of the formula —CH₂CH₂—O—R′, where R′ is as defined for R with the proviso that R′ has at least 3 carbon atoms.

Particularly suitable alkoxylate groups are those in which m and n are each numbers from 0 to 30, especially from 0 to 15. The sum m+n is preferably at least 6, in particular at least 8. A¹ and A² are groups derived from butylene oxide and, especially, from propylene oxide and from ethylene oxide. Pure ethoxylates and pure propoxylates are of particular interest, although ethylene oxide-propylene oxide block structures may also occur.

If there is any substitution on the phenyl rings, there are preferably two (identical or different) substituents or, in particular, a single substituent.

Examples of phenylalkyl groups are 5-phenylpentyl, 6-phenylhexyl, 8-phenyloctyl, 10-phenyldecyl or 12-phenyldodecyl.

If there is any substitution on the phenyl rings, the substituents are preferably groups which confer solubility in water, such as hydroxyl groups, carboxyl groups or sulfo groups.

Component (B) is preferably present in the textile detergent formulation according to the invention in an amount of from 2 to 30% by weight, in particular from 3 to 20% by weight.

The anionic surfactants (C) are, in principle, taken to mean any anionic surfactants that are structurally different from Compounds I.

In a preferred embodiment, the weight ratio of (B) glycine-N,N-diacetic acid derivatives I to the anionic sufactants (C) in the solid textile detergent formulation according to the invention is from 50:1 to 1:2, preferably from 20:1 to 1:1. The detergent formulation according to the invention is particularly effective in this ratio range.

Examples of suitable anionic surfactants (C) are fatty alcohol sulfates of fatty alcohols having from 8 to 22, preferably from 10 to 18, carbon atoms, eg. C₉- to C₁₁-alcohol sulfates, C₁₂- to C₁₄-alcohol sulfates, C₁₂- to C₁₈-alcohol sulfates, lauryl sulfate, cetyl sulfate, myristyl sulfate, palmityl sulfate, stearyl sulfate and tallow fatty alcohol sulfate.

Further suitable anionic surfactants are sulfated ethoxylated C₈- to C₂₂-alcohols (alkyl ether sulfates) and their soluble salts. Compounds of this type are prepared, for example, by firstly alkoxylating a C₈- to C₂₂-, preferably a C₁₀- to C₁₈-, alcohol, eg. a fatty alcohol, and subsequently sulfating the alkoxylation product. For the alkoxylation, it is preferable to use ethylene oxide, 1 to 50 mol, preferably 1 to 20 mol of ethylene oxide being employed per mole of alcohol. It is, however, also possible to alkoxylate the alcohols using propylene oxide alone or, if desired, together with butylene oxide. Also suitable are those alkoxylated C₈- to C₂₂-alcohols which contain ethylene oxide and propylene oxide or ethylene oxide and butylene oxide or ethylene oxide and propylene oxide and butylene oxide. The alkoxylated C₈- to C₂₂-alcohols can contain the ethylene oxide, propylene oxide and butylene oxide units in the form of blocks or in random distribution. Depending on the nature of the alkoxylation catalyst, alkyl ether sulfates of broad or narrow alkylene oxide homolog distribution can be obtained.

Further suitable anionic surfactants are alkanesulfonates, such as C₈- to C₂₄-, preferably C₁₀- to C₁₈-, alkanesulfonates, and also soaps, for example the Na and K salts of C₈- to C₂₄-carboxylic acids.

The anionic surfactants are preferably added to the detergent in the form of salts. Suitable cations in these salts are alkali metal ions, such as sodium, potassium and lithium and ammonium salts, for example hydroxyethylammonium, di(hydroxyethyl)ammonium and tri(hydroxyethyl)ammonium salts.

Component (C) is preferably present in the novel textile detergent formulation in an amount of from 0 to 4% by weight, in particular from 0.1 to 4% by weight. Examples of amounts frequently used are from 0 to 0.3% by weight, 0.5% by weight, 1.5% by weight, 2% by weight, 2.5% by weight and 3.5 to 4.5% by weight.

It is possible to use individual anionic surfactants or a combination of different anionic surfactants. It is possible to use anionic surfactants from only one class, for example only fatty alcohol sulfates or only alkylbenzenesulfonates, or mixtures of surfactants from different classes, eg. a mixture of fatty alcohol sulfates and alkylbenzenesulfonates.

The use of biodegradable glycine-N,N-diacetic acid derivatives I, which also have an incrustation-inhibiting effect, also makes it possible to reduce the content of inorganic builders (A) (in particular alumosilicates, silicates) and thus to provide concentrated detergent formulations which contain a higher content of biodegradable components.

Accordingly, in a further preferred embodiment, the solid textile detergent formulation according to the invention contains a greatly reduced content of silicate builders, namely:

from 1 to 30% by weight, preferably from 5 to 27% by weight, of carbonate-based inorganic builders,

from 0 to 12% by weight, preferably from 1.5 to 8% by weight, in particular from 2 to 6% by weight, or preferably from 0 to 0.5% by weight, of inorganic builders based on crystalline or amorphous alumosilicates and/or crystalline or amorphous silicates and

from 0 to 5% by weight, preferably from 0.05 to 2% by weight, of phosphate-based inorganic builders.

Examples of suitable nonionic surfactants (D) are alkoxylated C₈- to C₂₂-alcohols, such as fatty alcohol alkoxylates or oxo alcohol alkoxylates. The alkoxylation can be carried out using ethylene oxide, propylene oxide and/or butylene oxide. Surfactants which can be used are all the alkoxylated alcohols which contain at least two adducted molecules of one of the aforementioned alkylene oxides. Also suitable are block polymers of ethylene oxide, propylene oxide and/or butylene oxide or addition products which contain said alkylene oxides in random distribution. From 2 to 50, preferably from 3 to 20, mol of at least one alkylene oxide are used per mole of alcohol. The alkylene oxide used is preferably ethylene oxide. The alcohols preferably have 10 to 18 carbon atoms. Depending on the type of alkoxylation catalyst, it is possible to obtain alkoxylates with a broad or narrow alkylene oxide homolog distribution.

A further class of suitable nonionic surfactants comprises alkylphenol alkoxylates, such as alkylphenol ethoxylates having C₆- to C₁₄-alkyl chains and from 5 to 30 mol of alkylene oxide units.

Another class of nonionic surfactants comprises alkyl polyglucosides having from 8 to 22, preferably from 10 to 18 carbon atoms in the alkyl chain. These compounds usually contain from 1 to 20, preferably from 1.1 to 5, glucoside units.

Another class of nonionic surfactants comprises N-alkylglucamides having the structures

where B¹ is C₆- to C₂₂-alkyl, B² is hydrogen or C₁- to C₄-alkyl and D is polyhydroxyalkyl having from 5 to 12 carbon atoms and at least 3 hydroxy groups. Preferably, B¹ is C₁₀- to C₁₈-alkyl, B² is CH₃ and D is a C₅- or C₆ radical. Such compounds are obtained, for example, by acylating reductively aminated sugars using acid chlorides of C₁₀- to C₁₈-carboxylic acids.

Further suitable nonionic surfactants are the terminally-capped fatty acid amide alkoxylates, known from WO-A 95/11225, of the formula

It is possible to use individual nonionic surfactants or a combination of different nonionic surfactants. It is possible to use nonionic surfactants from only one class, in particular only alkoxylated C₈- to C₂₂-alcohols, or mixtures of surfactants from different classes.

Examples of suitable bleach catalysts are quaternized imines and sulfoneimines, which are described, for example, in U.S. Pat. No. 5,360,569 and EP-A 453 003. Particularly effective bleach catalysts are manganese complexes, which are described, for example, in WO-A 94/21777. Where used, such compounds are incorporated into the detergent formulations in amounts of up to 1.5% by weight, in particular of up to 0.5% by weight; in the case of very active manganese complexes, amounts of up to 0.1% by weight are used.

In addition to the described bleaching system comprising bleaching agents, bleach activators and, if required, bleach catalysts, it is also possible to use systems having enzymatic peroxide release or photoactivated bleaching systems for the novel textile detergent formulation.

In another preferred embodiment, the novel textile detergent formulation additionally comprises from 0.05 to 4% by weight of enzymes (H). Enzymes which are preferably used in detergents are proteases, amylases, lipases and cellulases. Preferred quantities of the enzymes are from 0.1 to 1.5% by weight, in particular from 0.2 to 1.0% by weight, of the formulated enzyme. Examples of suitable proteases are Savinase and Esperase (manufacturer: Novo Nordisk). An example of a suitable lipase is Lipolase (manufacturer: Novo Nordisk). An example of a suitable lipase is Lipolase (manufacturer: Novo Nordisk). An example of a suitable cellulase is Celluzym (manufacturer: Novo Nordisk). It is also possible to use peroxidases to activate the bleaching system. It is possible to use individual enzymes or a combination of different enzymes. If required, the novel textile detergent formulation can also contain enzyme stabilizers, for example calcium propionate, sodium formate or boric acids or salts thereof, and/or antioxidants.

The novel textile detergent formulation is solid, ie. is usually in powder or granule form or in the form of extrudates or tablets.

The novel pulverulent or granular detergents may contain up to 60% by weight of inorganic extenders. Sodium sulfate is usually used for this purpose. However, the content of extenders in the novel detergents is preferably low and is only up to 20% by weight, particularly preferably only up to 8% by weight, particularly in the case of compact or ultracompact detergents. The novel solid detergents may have various bulk densities in the range from 300 to 1300 g/l, in particular from 550 to 1200 g/l. Modern compact detergents generally have high bulk densities and are granular. To achieve the desired compaction of the detergents, it is possible to use the techniques customary in the art.

The textile detergent formulation of the invention is prepared and, if desired, packaged in accordance with customary methods.

Determination of the primary detergency

The primary detergency tests were carried out using the detergent formulations (DF 1 to 5) detailed in Table 1. Table 2 gives the washing conditions.

TABLE 2 Washing conditions: primary detergency Washing machine: Launder-o-meter from Atlas, Chicago, USA Liquor volume: 250 ml Washing duration: 30 min at 60° C. Detergent concentration: 4.0 g/l Water hardness: 3 mmol/1 Ca:Mg = 4:1 Liquor ratio: 12.5:1 Test fabric: WKF 10D, WKF 20D (WKF-Testgewebe GmbH, D-41379 Brüggen-Bracht) EMPA 101, EMPA 104 (Eidgenössische Materialprüfanstalt, St. Gallen, Switzerland)

The washed test fabrics were measured using a Datacolor photometer (ElrephoO 2000). The total remission values for all four types of fabric are given in percent in each case. The primary detergency is better the higher the remission value.

Results (primary detergency):

The results show that detergent formulations DP 3 to 5 according to the invention, which have a greatly reduced content of customary anionic surfactants (C), have a clearly better primary detergency than the traditional standard compact detergent formulations DF 1 and 2 (for comparison purposes). The AGDAs bind Ca and Mg ions and thus have an incrustation-inhibiting effect. In view of this ability, the use of AGDAs also makes it possible to reduce markedly the content of inorganic silicate builders (eg. zeolites, sheet silicates, amorphous disilicates), without any loss in performance.
